Seven scientifically-backed progression strategies adjust your weights, volume, and intensity every session. See where you stand. Challenge rivals. Join raids. Every system underneath makes consistency feel inevitable.
Every program runs one of seven progression strategies. Your weights, volume, and intensity adjust automatically based on your performance. No guesswork. No spreadsheets. Just progress.
Fixed weight increases every session. Simple. Effective. The foundation of all strength.
Hit the rep ceiling, earn the weight bump. Self-regulating and foolproof.
Light, medium, heavy weeks in rotation. Fatigue managed automatically.
Autoregulated by how you feel. Bad day? It adjusts. Good day? It pushes.
5/3/1, nSuns, Juggernaut. Per-set intensity prescriptions with AMRAP feedback.
Undulating volume across sessions. High days and low days, all calculated.
Progressive overload is the single most important driver of muscular adaptation. Without it, training stimulus stagnates regardless of effort.

Raid bosses scale to your party size. Every workout chips away their HP. PRs deal critical hits. Miss a session? The boss heals. You can't let your squad down.
Raid bosses are week-long cooperative challenges. Your party of up to 12 athletes deals damage through workouts, PRs, and streaks. Miss a day and the boss heals. Three escalating phases push your squad to the limit.
